Let's start by solving for side y using trigonometric ratios, specifically cosine.


cos(30)=(y)/(8)

We can solve for y by multiplying 8 to both sides of the equation.


y=6.9282

Let's solve for side x using trigonometric ratios, and this time we'll be using sine.


sin(30)=(x)/(8)

Multiply both sides of the equation by 8.


x=4

We have solved for the missing variables x and y:

x = 4 and y = 6.9
